Port Status LEDs
Port Status LEDs above each of the sixteen (16) RJ-45 lobe port
connectors indicate insertion status for each of the sixteen connections:
green LED:
good insertion
NOTE: Illuminated LEDs indicate insertion EXCEPT when a wrong speed
station is plugged into the hub; when a wrong speed station is plugged
into the hub, the iluminated LED indicates only that the connecting cable
is good.
Management Board LEDs
When the SNMP Management circuit board is installed and managing the
StackMaster™TR 16-Port Stack, the SNMP Management circuit board
indicators are active. The Enable indicator is illuminated when the SNMP
Management circuit board is installed. The eight Management Status
indicators cycle in a steady roll when the StackMaster™TR 16-Port Stack
is functioning normally.
